I started this last year. For the record, the answer is loop-AES-v3.2c, the readme and the comments in build-initrd.sh. There is some elaboration on the documentation in a Gentoo how to: http://gentoo-wiki.com/HOWTO_loop-AES_LVM2_root_partition. Basically the technique is to put logical volumes onto partitions, loop-aes loopbacks on these and file systems over the top. Thanks to Jari for working this out. Regards Fog_Watch. -- Lose wait.
